Solution

The correct option is B ${C H}_{3} {C H}_{2} O H$
Alcoholic group is present in ethanol ${C H}_{3} {C H}_{2} O H$

$- O H$ group (attached to aliphatic $C$ atom) is an alcoholic group.

${C H}_{3} C O O H$ contains the carboxylic group ( $- C O O H$ group). $C_{6} H_{5} O H$ contains phenolic $- O H$ group ( $- O H$ group attached to aromatic $C$ atom).

$H - O H$ is a water molecule.
